Underwater photography has a 120 year-old history in fact it goes back, and we actually have this pioneer Frenchman in the late 1890s who took a huge camera made a water-proof case and went underwater to take pictures of marine life but that was an inspiration for many people following and particularly in the last 60 years when free diving, scuba diving is developed photography is just sort of, carried on, it really is how we see the underwater world it’s the photographer and the research worked link to the public to be able to photography, to be able to film the underwater world and show what it’s like encouraging other people to visit of course, as well But for Maritime Archaeologists, and that’s my speciality photography for Maritime Archaeology it’s a way of bringing our past, our past of shipwreck excavation move forward in time, the fact we can revisit the wreck site through photography We, and anyone else for decades afterwards When photography began existing cameras were put in waterproof boxes not always waterproof, they would often leak but that’s crux we have to bear as underwater photographers everything leaks eventually but we took existing cameras in housing and here we have several examples of these for 20 years this was the Rolls Royce of underwater cameras designed by a very well known pioneer, Hans Hass but a camera that was superb to use it’s the camera which obviously now not in the housing but it made a bulky… bulky unit to have to work with and the underwater photographer could change when this camera came out camera that was waterproof to 50 metres, could just slung around the neck, carried with you always and it really, that freed up underwater photography although not freed up as much as the modern environments, which in the last ten years is digital, where we’ve gone from using film to the digital record and digital cameras have have freed up photography as never before now, the quality of underwater photographs from even a beginner is better than we who have 40 years experience could get in the past, so that’s changed things enormously I’m still, many of us are still using cameras in waterproof housing this is a very high quality digital single lens reflex camera but this housing allows me to use a whole range of lenses allows me to do almost all things underwater that I can do above water that means very wide angle photographs, that means extreme close-up photographs, so that is the sort of, I guess Rolls Royce of use these days. The thing that has really changed is small digital camera. Already it’s starting to get bulky again, but here I have two cameras two identical cameras in underwater camera cases these are good level – high level but compact digital cameras and this is for doing stereo for 3D photography that’s something that I have done, that we have done in the WA Museum department of Maritime Archaeology for 35 years now is record our wreck sites in 3D so that we can actually see a 3D view of the underwater world forever and into the future, and they are just two cameras that fire together this has a special viewfinder that I’ve added. Very wide angle lenses to cut through the water, for us to be able to see clearly in water and two are fired together as simple as that. I mean that gives the simulation of the left eye and the right eye they can viewed on a 3D television, or a 3D viewer, and it’s like having a physical model in front you that you can see in 3D. These cameras can also just be taken off and used, just like that. And that is really the model equivalent of the best of the film cameras so Nikonians camera there that was our main photographic tool for many years but now as superb as they are the quality is superb, that it’s replaced totally now by digital.
